Crypts of Lieberkuhn are involved in

Options

A. Secretion of succus entericus
B. Secretion of rennin
C. Secretion of ptyalin
D. digestion of food

Answer

**Step-by-Step Solution:**

1. **Understanding Crypts of Lieberkuhn**: Crypts of Lieberkuhn are tubular glands located in the small intestine. They are situated between the villi, which are finger-like projections that increase the surface area for absorption.

2. **Identifying the Cells**: The cells found in the crypts of Lieberkuhn are known as Paneth cells. These cells play a crucial role in the function of the crypts.

3. **Function of Paneth Cells**: Paneth cells are responsible for secreting antibacterial substances, particularly lysozyme. This secretion helps protect the intestinal lining from harmful bacteria.

4. **Role in Digestion**: The crypts of Lieberkuhn also contribute to the secretion of intestinal juices, known as succus entericus, which contain enzymes and other substances that aid in digestion.

5. **Conclusion**: Given the functions of the crypts of Lieberkuhn and the role of Paneth cells, the correct answer to the question is that they are involved in the secretion of succus entericus.

**Final Answer**: The crypts of Lieberkuhn are involved in the secretion of succus entericus.
